🔧Technical Breakdown
The attack exploited vulnerabilities in SonicWall’s cloud backup infrastructure. Initial investigations indicate that attackers leveraged a zero-day vulnerability, allowing them to bypass authentication mechanisms and gain unauthorized access to the backup service. The breach involved:
- **Exploitation Methodology:** Attackers likely used reverse engineering techniques to identify the vulnerability within the cloud service.
- **Access and Escalation:** Once access was gained, the attackers could move laterally across the system to escalate privileges, allowing them to access sensitive files and data.
- **Data Extraction:** The compromised systems allowed attackers to exfiltrate encrypted credentials and configuration data, raising concerns over targeted attacks on affected clients.
